Fig. (3 is afront elevation showing my attachments mounted on; a .desk telephone and ready for use, andshowii gflthetsioilndamplifier attached to the recei verwhlenit. is in its normal position of rest ongthetswitchhook, instead of being inverted asinjFig. 1. Figs. 1 to 5 of the dra il in'gs' how one form of my inventioncompr ising a soundamplifier, 1, attached by its eupsshaped end, 2, to the mouth of the receiizerfg a bracket,

attached adjacent to theswitch-hookof thecam, 5, flat strips 6 and fa, fpin,l8. by which thecam 5 is rotated and a holder torthe receiver, 9, attached rigidlyto the fiat strips 6 and 'i'. v The sound-amplifier is'at taehedat -itscupshaped end 2, to the mouth of the receiver 3 and held rigid againstthe outer ri n- 12 of the mouth "of the receixrer by ithe screws '10 and 11 of which there isaplurality, passing through the rim of theenp-shaped'endQ of the sound-amplifier. hed to th is cupshaped end, 2, of the ampl fier 1,;isQ its tubular part 13, communicating with-the eupshaped end 2 and through it with .the receiver, 3, without touching the diaphragm thereof. The tubular part, 13, of thesaid amplifier 1, terminates 1h;a trtl;mpet, 114;, and the amplifier 1, is by appropriateconformation, so shaped that the trumpet, 1:4,, thereof will be in juxtaposition tp the-v ear the speaker, when in theactofrtalkinginto the transmitter, 15 of the telephoner m strips 6 and 7 by the screws 20, 21, 22, and 23, and extends substantially at right-angles to the flat strips 6 and 7 toward the lower end of the receiver 3 when the receiver is on its rack, and is adapted to engage the receiver and hold it in a vertical position.

lVhen it is desired to make a telephonic connection, the pin 8 is turned whereby the cam 5, lifts the switch-hook into the position it would occupy if the receiver were remow'ed from its rack; and when it is desired to break the telephonic connection, the pin 8 is turned in the opposite direction, whereby the flattened part of the cam is upward, thus allowing the switch-hook to fall into the position it normally occupies when supporting the receiver.

,Fig. 6 shows a modification in the use of t sound-amplifier when it is desirable to attach it to the receiver of a telephone without inverting the receiver on its rack; the advantage being only more nearly perfect stability and more pleasing appearance. It will be seen therefore, that my attachments can be readily aflixed' to any telephone and that they are adapted for use as permanent attachments.

The advantages of my device are also obvious. The peculiar conformation of thesound-amplifier enhances the acoustic effects of the telephone receiver so that actual contact of the ear to the trumpet-end of the amplifier is not necessary, wherefore the speaker need not run the risk of infection thus providing a sanitary precaution especially desirable in a telephone in'more or less public use, in which the ordinary receiver is constantly exposed to disease germs, etc.

The chief advantage and purpose of my device is, however, inthe saving of time for the person using" the telephone equipped with my attachments. In order to make the connection, it'is necessary only to rotate the cam 5 by turning the pin 8. Instantly the switch-hook is raised and the connection made, allowing the person desiring to carry on a telephonic conversation the free use of both hands during the entire conversation, while waiting for the person at the other end of the line to come to his telephone, and during all interruptions in the conversation. At the conclusion of the conversation the connection is as quickly and easily broken by rotating the cam 55, in the opposite direction, whereby the switch-hook of the phone is again lowered.

While I have illustrated and described only one specific embodiment of my invention, having especially in mind the type of telephone called des (-phone, I am aware that it is susceptible of modifications and of adaptability to the ordinary wall telephone, the pay-station telephone, the telephone exchange systems and everv other kind of teletion w ile the telephone is being used.
